Mexico City - Mexico City has marked its 1,000th same-sex marriage since lawmakers in the capital approved such unions in March 2010.

The city government said in a statement that about 6 percent of those getting married in same-sex weddings in the city are foreigners.

Officials had predicted an influx in tourism when they enacted the first law in Latin America explicitly allowing same-sex marriages.

The first 1,000 weddings involved 548 gay couples and 452 lesbian pairs. About 85 percent of the marriages were between partners age 31 and older. Mexico's average marriage age is 28 for men and 25 for women.

The 1,000th wedding took place on Sunday, August 14, uniting a 37-year-old Mexican university researcher and a 29-year-old Dutch man.
